JP 2010-48378 A

  However, in manufacturing the strut mount of Patent Document 1, if the flange is integrally formed with the inner cylinder member, after the elastic body is fixed to the outer cylinder member and the inner cylinder member by vulcanization adhesion, Therefore, it is necessary to configure the flange separately from the inner cylinder member. Therefore, there is room for improvement from the viewpoint of reducing the number of parts and thus cost.

  On the other hand, in the strut mount of Patent Document 1, if the flange is configured integrally with the inner cylinder member, the elastic body is not fixed to the inner cylinder member and the outer cylinder member by vulcanization adhesion when the strut mount is manufactured. It is also conceivable to insert an elastic body between the inner cylinder and the outer cylinder member. However, in this case, only the force in the compression direction acts on the elastic body in response to the input to the strut mount in a direction perpendicular to the axial direction (hereinafter also referred to as “axial direction”). As a result, the spring constant in the direction perpendicular to the axis may be greatly reduced because the force in the tensile direction stops working.

To
According to the strut mount of the present invention, the cost can be reduced while obtaining a high spring constant in the axial direction.

  In the strut mount of the present invention, it is preferable that the inner cylinder member and the plate member are fixed to each other. According to this structure, the operation | work which attaches a strut mount to the piston rod of a shock absorber becomes easy.

  In the strut mount of the present invention, it is preferable that the surface of the plate member bonded to the elastic body by vulcanization includes a portion facing the outer peripheral side. According to this configuration, the spring constant in the direction perpendicular to the axis can be further increased.

The strut mount manufacturing method of the present invention includes an outer cylinder member attached to a vehicle body, a cylindrical part provided on the inner peripheral side of the outer cylinder member, and an end part on one axial side of the cylindrical part.

  According to the present invention, it is possible to provide a strut mount and a manufacturing method thereof that can reduce the cost while obtaining a high spring constant in the axial direction.

It is sectional drawing which follows one central axis which shows one Embodiment of the strut mount of this invention. It is sectional drawing which shows the strut mount of FIG. 1 in the state attached to the piston rod of a vehicle body and a shock absorber along a central axis. It is a figure for demonstrating an example of the method of manufacturing the strut mount of FIG.

Hereinafter, embodiments of a strut mount according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of the strut mount 1 according to the present embodiment, taken along the central axis O. FIG. 2 shows the strut mount 1 according to the present embodiment as a piston rod for a vehicle body 50 and a shock absorber (not shown). FIG. 6 is a cross-sectional view taken along the central axis O, shown in a state attached to 60. The strut mount 1 of the present embodiment suppresses transmission of vibration transmitted from the tire to the piston rod 60 of the shock absorber to the vehicle body 50. The strut mount 1 of the present embodiment is preferably used for a tire on the front side of the vehicle body, but may be used for a tire on the rear side of the vehicle body.

The strut mount 1 according to the present embodiment includes an outer cylinder member 10, an inner cylinder member 20, a plate member 30, and an elastic body 40. The central axis O of the strut mount 1 is the same as the central axis of the inner cylinder member 20.
The strut mount 1 is attached to the vehicle such that the direction along the central axis O is, for example, the vertical direction of the vehicle body. In this case, the directions perpendicular to the central axis O correspond to the front-rear direction and the left-right direction of the vehicle body.
In the following, the direction along the central axis O is referred to as “axial direction”, and the upper side and the lower side in FIGS. 1 to 3 are referred to as “axial direction one side” and “axial direction other side”, respectively. The direction perpendicular to the center axis is referred to as “axial direction”, the side close to the central axis O is referred to as “inner side”, and the side far from the central axis O is referred to as “outer side”.

In this example, the outer cylinder member 10 includes a cylindrical cylindrical portion 11, an attachment portion 12 extending from the end on the other axial side of the cylindrical portion 11 to the outer peripheral side, and one axial direction of the cylindrical portion 11. And a flange portion 13 extending from the end portion to the inner peripheral side. As shown in FIG. 2, the attachment portion 12 is attached to the vehicle body 50 by, for example, bolts 51 and nuts 52. The flange portion 13 of the outer cylinder member 10 constitutes an end portion on one side in the axial direction of the outer cylinder member 10.
In addition, the flange part 13 may be extended from the edge part of the axial direction one side of the cylindrical part 11 to the outer peripheral side, or may be extended straightly along the axial direction.

  The inner cylinder member 20 is provided on the inner peripheral side of the outer cylinder member 10 and is cylindrical in this example, and a flange extending from the end on one side in the axial direction of the cylindrical part 21 to the outer peripheral side. Part 22. In this example, the inner cylinder member 20 further has a bottom 23 extending from the end on the other axial side of the cylindrical portion 21 to the inner peripheral side. The bottom portion 23 defines a through hole 23a penetrating along the central axis O by the inner peripheral side end portion.

  The flange portion 22 of the inner cylinder member 20 is positioned on one side in the axial direction with respect to the flange portion 13 of the outer cylinder member 10. And the outer peripheral side edge part of the flange part 22 of the inner cylinder member 20 has opposed the flange part 13 of the outer cylinder member 10 in the axial direction. The flange portion 22 of the inner cylinder member 20 is an end portion on one axial direction side of the outer cylinder member 10 when the inner cylinder member 20 is displaced to the other axial direction side with respect to the outer cylinder member 10 at the time of input in the axial direction. That is, in this example, it has a function as a stopper that restricts the displacement of the inner cylinder member 20 by hitting the flange portion 13.

In this example, the elastic body 40 covers the surface on one side in the axial direction of the flange portion 13 of the outer cylinder member 10, so that the flange portion 22 of the inner cylinder member 20 is placed outside via the elastic body 40. It is made to contact the flange part 13 of the cylindrical member 10. Thereby, generation | occurrence | production of the noise when the flange part 22 of the inner cylinder member 20 contacts the flange part 13 of the outer cylinder member 10 can be suppressed.
However, it is not essential for the elastic body 40 to cover the surface on one side in the axial direction of the flange portion 13 of the outer cylinder member 10, and the flange portion 22 of the inner cylinder member 20 directly contacts the flange portion 13 of the outer cylinder member 10. It may be made like.

  The plate member 30 is configured in a plate shape, and is provided on the other side in the axial direction with respect to the inner cylinder member 20. More specifically, in this example, the plate member 30 is superimposed on the bottom 23 of the inner cylinder member 20 from the other side in the axial direction. The plate member 30 has an inner peripheral side portion facing the bottom portion 23 of the inner cylinder member 20 in the axial direction (more specifically, in this example, contact), and an outer peripheral side portion of the plate member 30 of the inner cylinder member 20. It extends to the outer peripheral side from the bottom part 23 (as a result, the outer peripheral side from the cylindrical part 21). The plate member 30 is formed with a through hole 30 a that penetrates along the central axis O.

  In this example, the plate member 30 is caulked with respect to the inner cylinder member 20, whereby the inner cylinder member 20 and the plate member 30 are fixed to each other. More specifically, in the plate member 30, the inner peripheral side end portion 31 that defines the through hole 30 a is closer to the inner peripheral side than the inner peripheral side end portion that defines the through hole 23 a in the bottom portion 23 of the inner cylinder member 20. , Projecting to the one side in the axial direction, and at the projecting tip, the inner peripheral side end of the bottom 23 of the inner cylindrical member 20 is covered with the inner peripheral side end of the bottom 23 of the inner cylindrical member 20. On the other hand, it is crimped to the outer peripheral side. Thereby, in this example, the through-hole 30a of the plate member 30 is located in the inner peripheral side rather than the through-hole 23a of the inner cylinder member 20. FIG.

  As shown in FIG. 2, in this example, the piston rod 60 of the shock absorber is inserted from the other side in the axial direction into the through hole 30a of the plate member 30 (and hence the through hole 23a of the inner cylinder member 20). The plate member 30 is attached to the piston rod 60 together with the inner cylinder member 20. More specifically, in this example, a screw is formed at the distal end portion 60b of the piston rod 60 that has a smaller diameter than the through hole 30a of the plate member 30, and the distal end portion 60b is a through hole of the plate member 30. The main body portion 60a of the piston rod 60 that is inserted into the shaft 30a from the other side in the axial direction and has a larger diameter than the through hole 30a of the plate member 30 is applied to the plate member 30 from the other side in the axial direction. And the nut 61 is fastened with respect to the bottom part 23 of the inner cylinder member 20 from one axial direction side. Thereby, the plate member 30 and the inner cylinder member 20 are attached to the piston rod 60 in a state where the plate member 30 and the inner cylinder member 20 are sandwiched between the main body portion 60 a of the piston rod 60 and the nut 61.

The elastic body 40 is made of rubber, for example, and is disposed between the outer cylinder member 10 and the inner cylinder member 20. The elastic body 40 is formed with a through hole 40 a penetrating the central axis O, and the cylindrical portion 21 and the bottom portion 23 of the inner cylinder member 20 are disposed in the through hole 40 a of the elastic body 40.
As shown in FIG. 2, in a state where the strut mount 1 is attached to the vehicle body 50 and the piston rod 60 of the shock absorber as described above, the outer cylinder member 50 is moved to the plate member 30 and the inner cylinder member by a load from the vehicle body 50. 10, the distance between the outer cylinder member 50 and the plate member 30 is reduced.

The elastic body 40 is fixed to at least a part of the inner peripheral surface of the outer cylinder member 10 and at least a part of the surface on one side in the axial direction of the plate member 30 by vulcanization adhesion, and is not attached to the inner cylinder member 20. Have been glued. More specifically, in this example, the elastic body 40 is vulcanized and bonded to the inner peripheral surface of the cylindrical portion 11 of the outer cylindrical member 10 over the entire periphery, and the inner cylindrical member in the plate member 30 The entire outer periphery is vulcanized and bonded to the surface on one side in the axial direction of the outer peripheral side portion extending to the outer peripheral side from the 20 cylindrical portions 21. In this example, the elastic body 40 is also applied to the entire surface of the flange portion 13 of the outer cylinder member 10 (that is, the surface on one side in the axial direction, the end surface on the inner peripheral side, and the surface on the other side in the axial direction). It is vulcanized and bonded around the circumference.
On the other hand, in this example, the elastic body 40 is in non-adhering contact with a portion of the outer peripheral surface of the cylindrical portion 21 of the inner cylindrical member 20 in the axial direction, and the cylindrical portion of the inner cylindrical member 20 The other part of the outer peripheral surface of 21 is not in contact. Note that the elastic body 40 may or may not be in contact with the inner cylinder member 20 as long as the elastic body 40 is not bonded to the inner cylinder member 20. Here, “being non-adhered to the inner cylinder member 20” means that there is no portion bonded to the inner cylinder member 20.

  If the elastic body 40 is not bonded to any of the inner cylinder member 20, the outer cylinder member 10, and the plate member 30, it is elastic with respect to the input to the strut mount 1 in the direction perpendicular to the axis. Only a force in the compression direction acts on the body 40, and no force in the tension direction acts on the body 40. On the other hand, in this example, the elastic body 40 is bonded to the outer cylinder member 10 and the plate member 30 by vulcanization, so that the elastic body 40 is compressed in the compression direction with respect to the input to the strut mount 1 in the axial direction. In addition to this force, a force in the tensile direction also acts, so that the spring constant in the direction perpendicular to the axis can be increased accordingly. In addition, in each of the inner peripheral surface of the outer cylinder member 10 and the surface on one side in the axial direction of the plate member 30, the more the portion that is vulcanized and bonded to the elastic body 40, the more the spring constant in the axial direction is Get higher.

  The elastic body 40 may be vulcanized and bonded to the inner peripheral surface of the cylindrical portion 11 of the outer cylinder member 10 over only a part in the circumferential direction, and the surface on one side in the axial direction of the plate member 30. On the other hand, it may be vulcanized and bonded over only a part in the circumferential direction. For example, the axial direction of the elastic body 40 on the inner peripheral surface of the cylindrical portion 11 of the outer cylindrical member 10 and the outer peripheral side portion of the plate member 30 extending to the outer peripheral side from the cylindrical portion 21 of the inner cylindrical member 20. For example, vulcanization bonding may be performed only on the circumferential portion corresponding to the front-rear direction of the vehicle body, with respect to each of the one side surfaces. In this case, the spring constant in the front-rear direction of the vehicle body can be made higher than the spring constant in the left-right direction of the vehicle body.

In this example, the plate member 30 is formed so as to rise once to the one side in the axial direction and then descend to the other side in the axial direction while moving toward the outer peripheral side in the portion bonded to the elastic body 40. A raised portion 32 is provided. The surface of the plate member 30 that has been vulcanized and bonded to the elastic body 40 includes a portion 30 b that faces the outer peripheral side along the descending portion of the raised portion 32. According to this, for example, the distance between the outer cylinder member 10 and the plate member 30 is reduced compared to the case where the plate member 30 is flat along the axial direction at the portion where the elastic member 40 is bonded. The compression force and the tensile force acting on the elastic body 40 between the plate member 30 and the outer cylinder member 10 can be increased with respect to the input to the strut mount 1 in the direction, and thus in the direction perpendicular to the axis. The spring constant can be further increased.
Instead of having the raised portion 32, the plate member 30 is lowered to the other side in the axial direction without being raised to one side in the axial direction while going to the outer peripheral side in the portion bonded to the elastic body 40. And may have a descending portion. Even in that case, the surface of the plate member 30 that is vulcanized and bonded to the elastic body 40 includes the portion 30b that faces the outer peripheral side along the descending portion, so that the spring constant can be increased.

  2, in the state where the strut mount 1 is attached to the vehicle body 50 and the piston rod 60 of the shock absorber, the portion 30b of the plate member 30 facing the outer peripheral side, and the outer cylinder member 10 It is preferable that the inner peripheral surface of the cylindrical portion 11 is at least partially opposed to the axial direction. With this configuration, it is possible to further increase the compressive force and tensile force acting on the elastic body 40 between the plate member 30 and the outer cylinder member 10 with respect to the input to the strut mount 1 in the axial direction. As a result, the spring constant can be further increased.

Next, an example of a method for manufacturing the strut mount of this embodiment will be described with reference to FIG. The manufacturing method of the strut mount of this embodiment can be used suitably for manufacturing the strut mount 1 of this embodiment mentioned above. Below, the case where the strut mount 1 of this embodiment mentioned above is manufactured is demonstrated.
First, the outer cylinder member 10 and the plate member 30 are set in a mold for vulcanization molding (not shown). At this time, in this example, the inner peripheral side end portion 31 of the plate member 30 protrudes straight along the axial direction.
And before or after setting the outer cylinder member 10 and the plate member 30 in the mold, at least a part of the inner peripheral surface of the outer cylinder member 10 (in this example, a part extending over the entire circumference) and the plate member 30 An adhesive is applied to at least a part of the surface on one side in the axial direction (in this example, a part extending over the entire circumference).

Thereafter, an elastic material is injected into the mold, and the elastic body is integrally vulcanized with the outer cylinder member 10 and the plate member 30. As a result, the elastic body 40 is applied to a portion of the inner peripheral surface of the outer cylinder member 10 where the adhesive is applied and a portion of the surface on one side of the plate member 30 where the adhesive is applied. While being fixed by vulcanization adhesion, a through hole 40a penetrating in the axial direction is formed in the elastic body 40 by the mold (vulcanization molding step).
Thereafter, the elastic body 40, the outer cylinder member 10, and the plate member 30 fixed integrally with each other are extracted from the mold.

  Next, as shown in FIG. 3, the cylindrical portion 21 (and the bottom portion 23a) of the inner cylindrical member 20 is inserted into the through hole 40a of the elastic body 40 from one side in the axial direction (insertion step). At this time, in this example, the inner peripheral end 31 of the plate member 30 that protrudes to one side in the axial direction is inserted into the through hole 23 a of the inner cylinder member 20.

Here, as in this example, the inner diameter of the through hole 40a of the elastic body 40 before the inner cylinder member 20 is inserted into the through hole 40a of the elastic body 40 is at least a part of the axial direction of the through hole 40a (this In the example, it is preferable that only a part thereof is slightly smaller than the outer diameter of the cylindrical portion 21 of the inner cylindrical member 20. In this case, in the insertion step, the cylindrical portion 21 of the inner cylinder member 20 is press-fitted into the through hole 40 a of the elastic body 40. As a result, the inner cylinder member 20 can be made difficult to move in the through hole 40a of the elastic body 40, so that the work of assembling the strut mount 1 (for example, a fixing step described later) performed thereafter, The operation of attaching to 30 and the piston rod 60 becomes easier.
However, in the insertion step, it is not essential that the cylindrical portion 21 of the inner cylinder member 20 is press-fitted into the through hole 40a of the elastic body 40, and before the inner cylinder member 20 is inserted into the through hole 40a of the elastic body 40. The inner diameter of the through hole 40a of the elastic body 40 may be greater than or equal to the outer diameter of the cylindrical portion 21 of the inner cylinder member 20 over the entire length of the through hole 40a in the axial direction.

After the insertion step, the inner cylinder member 20 and the plate member 30 are fixed to each other (fixing step). More specifically, in this example, the protruding tip end portion of the inner peripheral side end portion 31 of the plate member 30 is caulked against the inner peripheral side end portion of the bottom portion 23 of the inner cylinder member 20. By carrying out the fixing step, the inner cylinder member 20 is disengaged or displaced with respect to the plate member 30 until the strut mount 1 is subsequently attached to the vehicle body 30 and the piston rod 60, for example during transportation. Can be prevented. Thereby, the operation | work which attaches the plate member 30 and the inner cylinder member 20 to the piston rod 60 becomes easier. However, the fixing step may not be performed.
As described above, the strut mount 1 as shown in FIG. 1 is obtained.

According to the strut mount 1 of the present embodiment, since the flange portion 22 is integrally configured as a part of the inner cylinder member 20, the inner cylinder member and the flange are configured separately as in Patent Document 1 described above. Compared to the case, it is possible to reduce the number of parts and thus the cost. Furthermore, since the elastic body 40 is vulcanized and bonded to the outer cylinder member 10 and the plate member 30, a high spring constant in the axial direction can be obtained.
Moreover, according to the manufacturing method of the strut mount of this embodiment, the strut mount 1 which can reduce cost can be obtained, obtaining the high spring constant in the axial direction.

The strut mount 1 and the manufacturing method thereof according to the present embodiment are not limited to the above-described examples, and various modifications can be made. Moreover, the strut mount 1 of this embodiment can be manufactured also by methods other than the manufacturing method which concerns on the example mentioned above.
For example, in the fixing step, the inner cylinder member 20 and the plate member 30 may be fixed to each other by crimping the inner cylinder member 20 to the plate member 30. In that case, for example, instead of projecting the inner peripheral end 31 that defines the through hole 30a in the plate member 30 to one side in the axial direction, the inner peripheral end that defines the through hole 23a in the bottom 23 of the inner cylinder member 20 The portion is protruded to the other side in the axial direction on the inner peripheral side than the inner peripheral side end portion 31 of the plate member 30, and the inner peripheral side end portion 31 of the plate member 30 is covered with the protruding tip portion. What is necessary is just to caulk to the outer peripheral side.
In the fixing step, the inner cylinder member 20 and the plate member 30 may be fixed to each other by a method other than caulking. For example, the inner cylinder member 20 and the plate member 30 may be fixed to each other by projection welding. In that case, for example, one or more protrusions are formed on the surface on the other axial side of the bottom 23 of the inner cylindrical member 20 or the surface on the one axial side of the inner peripheral side portion of the plate member 30, and the inner cylindrical member 20 is formed. The above-mentioned fixing can be performed by applying a high voltage and pressure to the protrusion in a state where the bottom 23 of the plate and the inner peripheral side portion of the plate member 30 are overlapped.
